1KW 2km OTDR Bare Optical Fiber Ring Box SM MM Dummy Fiber SC FC LC Connectors
OTDR launch box, which is actually a long spool of optical fiber inserted between the fiber under test and OTDR,
can ensure that the OTDR dead zone happens in the OTDR launch box (shown in the following picture).
Then, the fiber optic link under test won't be largely affected by the OTDR dead zone.
The dead zone of OTDR, caused by high return level of reflection and affected by the pulse width,
might extend hundred meters from the OTDR.
Full length of optical fiber is suggested to use before the optical fiber under test.
Thus, the receiver of the OTDR can have enough time to settle.
Use this adapter for launching an OTDR or test set into an unconnectorized optical fiber
for loss or length verification. Adapter can be cleaned easily if fiber breaks off during use.
A fiber ring serves as both a launch cable and a receive cable.
They are also known as pulse suppressor cables, launch cords, launch leads, receive cables or fiber rings.
The OTDR Launch cables can be added with certain connectors,
such as FC-FC,SC-SC,FC-SC ST-ST etc.
Please send us your requirements for the connectors you need.
